Abstract (en)
The present invention aims to provide a tissue-function measurement device and a therapeutic device which are not dependent on tissue shape. According to the present invention, the stiffness of a tissue is measured by using, as an index, acoustic variation during the generation of microbubbles from phase-change nano droplets. The acoustic variation is, for example, a duration time of the generation of a harmonic.
